Title: Gas operated powder intake pipe - has concentric gas pipe producing conical current to loosen powder in vessel
IPC: B65G53/14
Filed: 1977-01-26
Abstract: The intake pipe is for transporting powder, using compressed propellant gas, and immersed in a vessel containing finely divided powder. It has an open-ended section for powder and gas, transporting the latter in suspension from the vessel to the position of use. A gas pipe is concentric to this section, to form an annular intervening gap, and has an opening near the section inlet, through which the gas is delivered into the latter. This produces a high-velocity converging conical current, loosening the powder in the vessel and suspending it in the gas current. The propellant gas is delivered into the gas pipe from a unit storing it under pressure.

Title: Pipe joint locator, counter and displacement calculator - has several sensors which develop signals passed to logical network and has plus and minus counters with numeric read=out display
IPC: E21B47/09
Filed: 1978-05-24
Abstract: There is a novel method and appts. for counting pipe joints, passing through a bell nipple, going downhole and uphole by sensing, at spaced apart positions along the nipple utilizing magnetic fields, for the presence of a joint. Each sensor develops signals as the joint passes it and a logical network which determines which direction the pipe joint is travelling, adds a plus count to the joint counter for joints going downhole and subtracts a mnus count from the joint counter when a joint is sensed coming uphole. Another logical circuit converts the joint count to a stand count.
